Applicatidn filed. December-18, 1914, Serial No. 877,

To all whom it may concern: Be it known that I, GEORGE ALBERT LYON,

- a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Bufiers for Motor- Cars, of which the. following is a specifica- 131011. I

My invention has been designed especially with the View of providing an effective form of buffer for application to the well-known Ford motor car without necessitating any change in the structure of the latter. Thebufier comprises opposite rigid longitudinal 'members for application to the side frames A of the car and a resilient member extending transversely across the front of the car from one of said rigid side members to the other. 1 The side members are so formed. and so mounted as to possess the maximum ofrigidity and the resilient member consists of a. bar or pair of bars bent so as to provide the desired amount of e1asticity,.the bar itself or the pair of bars, however, being so shaped in' cross section as to increase their resistance to bending'strain.

In theaccompanying drawings- Figure 1 is a planvie'w of my improved bufi'er structure with sufficient of the framework of the car to illustrate the application i of the buffer thereto;

Fig. 2 is a view, partly in side elevation and partly in section, on the line a-a,

Fig. 3 is a perspective view of a portion of one of the fixed members of the buffer looking from the under side of the same;

Fig; 5, is a transverse section on the line c'-0, Fig. 2;

Fig. 6 is a transverse section on the line d-d, Fig. 2;

Fig. 7 1s a view similar to Fig. 1, but illustrating a special form of resilient member of the buffer;

Figs. 1, 7 and. 11, Figs. 4., 5 and e are on a larger scale than Figs. 2, 3and 8, and Figs. 9 and '10 are on a larger scale than Figs. 1,.5and6.

The resilient member of the bufi'ershown in Fig.1 consists of two bars 1 and 2vex tending transversely across the front ofthe ear, the central portionsof these bars 'over lapping one another and being held in po sition by any suitable clips 3, each bar being then turned back on itself so 'as to form the j end loop 4 which is, by preference, bent, slightly to the rear, said'end loop- 4. termi natin at'the inner end of. its rear member. in a ow 5 whose-rear endis connected-to the rigid member 6 of the buflefl-the latter being secured tolthe forward end of onexof the side frames 7 of the can. In order that;

this connection of therigid member 6 of the,

bufi'er .to the 'frame of the carg-mayflbe-. effeeted without any alteration of the latter I mount said rigid, member in the following:

manner The headlight 8 is mounted upon an arm 9- which projects outwardly from a bracket 10,.

the latter bearing against the outer-side of the car frame 7 and against the unde'r'fiangev of the same and ;being secured to said under flange by means of a nut 11. member of the buffer comprisesthree parts 12, 13 and'l l, the forward and rear portions 13 and I l-being of right-aligled cross sec- The rigid i tion and the intermediate portion 12 being a horizontal plate which connects said forward and rear portions and rests upon the lamp arm 9 and its bracket 10, as shown, in

Fig. 4, being held firmly in contact with said lamp arm and bracket by means of a yoke 15 whose lower looped portion extends be? neath the horizontal portion of the bracket 10 and engages the'securing bolt 11 and its upwardly projecting ends passing through openings in the plate 12 and being threaded 1 the {top of said plate 12, as-shown in Figs. 2 and 4.

The back end of the vertical flange of the rear portion 14 of the rigid member of the -.for the reception of nuts which bear upon buffer extends down beneath the horizontal bottom flange of they side bar 7 ofthe car, as shown in Fig. 6, and is secured thereto by means of a bolt 16 passing through an opening with which the flange is-nsually pro-;;

vided at this point, said'bolt having a nut bearing'upon the top of the flange, as shown in Fig. 6. In order to stiffen and strengthen the rear end of the rigid member of the bufler the same has. a laterally projecting flange 17, as shown in Figs. 2-and 6.

T ne vertical flange of the forward portion 13 of the rigid member of the buffer is of' concavo-convex cross section at its front end,

as shown at 18 in Fig. 9,- and the bar 1 or, 2 of the resilient Inemberof the buffer which-- bears against said portion 13 of the rigid 4 member is likewise of concavo-convex cross section and is firmly bolted or riveted to the flange 18, as shown in Fig. 9. The concavoconvex cross section of the bars 1 and 2 continues throughout the entire length of the same and serves to stiffen the bar and enable it to better resist bending strains than would a flat bar, the resilience of the bufi'er as a whole being due to the loops 4 and bows 5 which act in the nature of springs.

In order to lessen the shearing strain, upon the lamp'arm 9 which might otherwise be caused when rearward pressure was exmembers of the automobile to extend ,for-" ward therefromand having angular front portions to engage said attaching members and bejremovably and rigidly connected thereto.

3. In automobile bufi'ers, the combination of-a Ford or similar automobile, a resilient bufi'er formed of wide thin spring strips to be relatively rigid vertically while-resilienty yielding in horizontal directions, said bu er comprising a reinforced transverse impact receiving portion, and connected rearwardly extending attaching members erted upon the bufi'eig, the vertical flange of the forward portion 13 of the rigid member of the bufi'er bears at its rear end against the forward end of the lamp arm bracket 10, as

shown in Figs. 2 and 8.

The bend 19 in the left hand rigid member of thebufier is formed therein in order to clear the nut which is present on-the left hand side frame of a car of the type for which my improved buiferhas been designed. I

The bars 1 and 2 comprising the resilihaving ends formed with a curved cross section for increased horizontal stiffness and substantially rigid flanged extension supporting members rigidly connected to the ably and flanged, frame members of the automobile to extend substantially in line therewith forward bevond the'ends thereofand removhaving curved section endslnto which-said attaching members are rigidly bolted tobe substantially in line therewith.

V *4. In automobile buffers, the combination of an automobile. a resilient bufi'er formed of ent memberjhthe bufi'er'shown in Fig. 7 are conca'vo-convex in cross section but instead" of presenting their convex faces in reverse directions in the looped portion 4 of the wide thin spring strip to be relatively rigid vertically while resiliently yielding inhorizrnta'l directions, said bufier comprising a trans\ ise' impact receiving portion and con- 'nect'ed rea'rwardly extending attaching memstructure, as in Figs. 1 and 2, they present said convex faces to the front both inthe front and rear, portions of said loop, as shown in Fig. 8, the end of the loop being fiat in cross section, as shown at 20 in Fig.7, and this is also true of the single bar resilient membershown in Fig. 11.
